Toluidine blue staining as an adjunctive tool for early diagnosis of dysplastic changes in the oral mucosa
Prognosis of oropharyngeal squamous cell carcinoma depends on early diagnosis, despite advanced surgical techniques, the 5-year survival rate remains ~40-50%. Unfortunately, it is usually detected when it becomes symptomatic. This requires treatment which gives rise to a high rate of morbidity and mortality and, furthermore, early detection of oro-pharyngeal pre-malignant lesions is important to improve the survival rate and quality of life. Since dysplasia and in situ carcinoma contain much more DNA and RNA than the normal surrounding epithelium, the use of in vivo staining, by means of toluidine blue dye, is based on the fact that it is an acidophilic dye that selectively stains acidic ti…
Osteosarcoma of maxilla: a case report
Osteosarcoma is a common primary malignant bone tumor producing osteoid or bone. It occurs very infrequently in the jaws and comprises of 4% of the tumour number as compared to the osteosarcoma of the long bones. Os- teosarcoma of the maxilla is even rarer presenting with common clinical features of pain and swelling. This pre- sented case is a rare case of osteosarcoma of maxilla in a 21-year-old female patient. Diagnosis and pre-operative assessment was performed using a combination of intraoral periapical radiograph, occlusal radiograph, paranasal view and computed tomography (CT). CT revealed destruction of the walls of maxillary sinus and sunray type of ossification in the soft tissues…
Oral Myiasis: a review
Myiasis is the infestation of tissues, organs of living vertebrate, animals and humans by certain dipterans fly larvae which feed on the host’s tissues and body fluids, often causing extensive damage to the host tissues if left untreated. Oral Myiasis is a rare pathology and is associated with poor oral hygiene, alcoholism, senility, suppurating lesions, severe halitosis. It arises from invasion of body tissues or cavities of living animals by maggots or larvae of certain species of flies. It occurs in tropical areas with poor living conditions and insufficient public and personal hygiene. Mouth-breathing during sleep, alcoholism, mental handicap, cerebral palsy and hemiplegia may facilitat…
Sonoporation, a redefined ultrasound modality as therapeutic aid: a review.
Traditionally a diagnostic modality, ultrasound is emerging as a promising tool for non-invasive therapy, drug delivery, and gene therapy. The ultrasound is a mechanical wave energy generated in a medium as oscillating pressure in space and time at frequencies above 20 kHz, beyond the audible range. The ultrasound exposure generates bioeffects resulting in tissue heating, shear stress, and cavitation, which have been exploited for therapeutic applications. Ultrasound cavitation, enhanced by injected micro bubbles, perturbs cell membrane structures to cause sonoporation and increases the permeability to bioactive materials. Ultrasound-mediated gene delivery has been applied to heart, blood v…
Probiotics. Going on the natural way.
Science is providing us the tools to diagnose and treat the infection before it causes damage. For some decades now, bacteria known as probiotics have been added to various foods because of their beneficial effects for human health. It comprises knowledge of the relationship between diet and health and the effects of food ingredients on physiological functions and health. Probiotics are commonly consumed as part of fermented foods with specially added active live cultures; such as in yogurt or as dietary supplements. The potential application of probiotics for oral health has recently been the focus of attention for various health researchers. The number of products containing probiotics en…
